There are several commands I often use, some of them are longer and it's a bit of a hassle to type them out (or look for them via arrow-up or CTRL-R) each time.
Are there ways (built-in or apps) to link them to a certain key combo, or some kind of favorites manager that allows easy access?
This all depends on the shell, of course.
For bash, you can use an alias:
alias foo="ls --color=always -l -Z --my-favourite-option" Now when you enter foo on the command line, bash will replace it with that long ls command line. This is valid until you exit your shell; if you wish for it to be permanent, you can add that command to ~/.bashrc, which will be executed by every started bash shell.
You can also create shortcuts by way of a .inputrc file. E.g., if you enter the following in a file ~/.inputrc:
"\C-\M-e": "echo this is a test" and then restart the shell, then whenever you hit control-alt-e, readline will enter that command.
Note, however, that since the inputrc file is parsed by libreadline (rather than by bash), it is used by every program that uses libreadline; so things like gdb and lftp will use it too, where running shell commands may not work.
